Viburnum plicatum f. plicatum 'Popcorn'

About this cultivar:

Viburnum plicatum f. plicatum 'Popcorn' is a viburnum thats pops! It grows somewhat smaller than typical f. plicatum plants and produces popcorn-like clusters of white flowers cover the shrub in a profuse spring bloom which occurs earlier than most other f. plicatum cultivars. The autumn colour is an attractive red to burgundy. First introduced by David Leach in 1994 this is a classic all over the world and justifiably so. In 2012 it was given the Royal Horticultural Society Award of Garden Merit.

David Leach also bred and introduced many superior rhododendrons, azaleas, magnolias and flowering shrubs. (His legacy continues at the 30-acre David G. Leach Research Station, a satellite of the Holden Arboretum in Madison, Ohio.).

About this genus:

Viburnum is a genus of about 150–175 species of shrubs or (in a few species) small trees in the moschatel family, Adoxaceae. The member species are native throughout the temperate Northern Hemisphere, with a few species extending into tropical montane regions in South America. Long popular in gardens one species, Viburnum tinus, was found depicted in the ruins of Pompeii – specially in a fresco in the House of the Wedding of Alexander. The genus name is what the romans called Viburnum lantana.

Viburnums are quite varied but generally bloom in April and May. They vary in their height, spread, and style of flower but are similar in preferring sun and part shade and in being disease and pest resistant. They will grow almost anywhere that isn’t waterlogged, and they can usually be controlled by pruning. Often they are paired with clematis (to add summer flowering interest)

While most flowers are unscented, those that are fragrant are wonderfully so. Some species also have a fringe of large, showy sterile flowers around the perimeter of the corymb to act as a pollinator target. An interesting source of diversity in the viburnums comes with the leaf shape and texture. The fruit is often also of visual interest, with red, to dark purple to black berries, which often serve as an important food source for birds.

Thus such diverse, tough, easy to grow, beautiful, disease resistant plants are ubiquitous in gardens. I once heard that if you can’t name an attractive shrub in a garden then ‘Viburnum’ is not a bad guess! Val Bourne has said “Every garden should contain at least one spring-flowering viburnum” and I couldn’t agree more.

The Tyrolean Iceman, the well-preserved-in-ice natural mummy of a man who lived between 3400 and 3100, was found with long, straight shoots of some viburnum. Presumably these shoots were used for arrows, however I like to think he was a pre-historic gardener just doing a spot of pruning…
